The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:

```Python

          assertThat(cookieB).isNotEqualTo(cookieA)
        }
      }
      assertThat(cookieA).isNotEqualTo(null)
    }
  }
